`Referring to thejdrawings, wherein for the p urpose of illustration is' shownapreferred embodiment o'f the invention, the letter A generally designates ,one of the ice containers embodying a vertically elongated casing 20 of rectangular cross section. The container casing is preferably to be of insulating construction andincludes, in addition toithefront, rear andside walls, a bottom-21 arranged to assume* aposition above the fioorline and atop plate 22. The top surface ofthe bottom or iloor structure-V21 is Idesigned to provide an inclination towardthe centre,`so that the drippin'gs fromtheV ice will iiow through a centrally disposed depending discharge pipe- 23.

The/ rear wall of the. container-casing 20 is providedrwithan lelevated filling opening normallyclosedby afhinged door 25.` The front and side -walls are formed, with relatively largev rectangularV shaped openings 26 arrangedlower than` the filling opening in` the rear and,kwhen not in use, are closed by means of removable covers 27.

In the Vupper portion lof the ice chamber is secured a'. horizontal partition plate 28` providedy witha plurality. of: apertures 29. The partition 28fis'disposedat a predetermined position below the topplate 22,to=providean upper compartment 30 in the container.4 A; Ventilating duct 3,1V is formed; through theupper portion` ofk the con-A tainer front `wall this Vduct affording communication bet'ween theicompartment and` the exteriorof thecontainerl.

, Secured in theverticalcornersof the container Wall structure andeirtending'fromy the bottom of the container to thepartition 28-l areI four Ybars 33;V provided in twov exterior facesthereof with longitudinal, vertically extendingchannels, 34. Slidablyand removably ttedin the channels 34 are aI plurality of flatelongatedfbarshaving the opposed longitudinal` edges indented, as-indi- Figure 9' is" a similar view with the door. in

`transverse sectionV takenv cated at 36, intermediate the ends. As shown to advantage at Figures 6 and 7, the bars 35 are disposed in horizontally extending superposed positions in oppositely arranged channels of the container and, in assembly, form therebetween narrow elongated interstices 37. Thus, the bars may be arranged to form interior barrier Vwalls inwardly of the filling opening of the container as well asthe' openings in the front and side Walls.

The container A constitutesa master ice-box which is to be usually supplemented by one or more, in the present instance two, auxiliary ice containers B. The containers B are constructed in correspondence with the master box Afwith the exception that the auxiliary boxes are of re'- form of elongated cases"C,preferably embodying a wood or metallic frame structure substantially rectangular in cross section.v The lcases C embody solid bottom flooring f39 ,'a rear wall 40and marginal end frames 41.` The rear wall 40 and, if desirable the flooringY 39 'and the end frame l, structures 41, may be of insulatingconstruction; 3o;

The casing frames are formed so that the top comprises a pair of parallel spaced-glass panes 42 and thefronta pair of similarpanes-43 providing transparent wall structures having 'deadair spaces between vthepanes.Y The rear wall of'ea'ch case C is provided With'a pair of relatively large door openings 44 normallyclosedV through the medium of hi-ngedly mounted doors 45 constructed to afford a substantially airtight connection when closed. The end frames 41 define relatively large rectangular shaped openings 46, approximately corresponding in shapel and size to the openings 26 inthe front and side walls of the ice containers. i

ARigidly mounted on each case C, at the junc- 45 tion of the rear wall and the topl transparent wall structure, is an elongated partition plate 47 extendng substantially the full length of the case and arranged transversely at an oblique angle so as to formin the upper rear portion an elongated corner'compartment 48 approximately triangular in crosfs'fsection. At longitudinally spacedV intervals, the partition platev 4 7 is provided with ventilatingl apertures 49. A lventilating duct Y50 t is formed throughtheupper portion vof the rear wall 40 of each case, providing apassage whereb y the compartment 48 communicates with the exterior. v Y l To assemble a plurality of container and provision case units to form 'a counter 'and display .U

box ofthe form shown atFigure '1, the covers 2 7 varei removedlfrom'the side openings' of the masterc'ontainer A andthe corresponding covers remove'd to uncover one side openingof each of f fg, th'e'auxiliary-containers VB. A pair of cases C are arranged'at each side of.l the masterV container and against :the side 'ofA each-of" the'auxiliary boxes, so as toprovide an alternate arrangement of boxes" and provision cases. 'In connecting theu boxes and cases,fthe ends of the cases may be initially-supported on transversely extending bars 52 secured k.to and extending transversely alongthe lower margin of the"r boxes and are thereafter boltedftothe adjacent sidewalls of the boxes by means of bolts 53 extended through the adjacent Ywalls about the margin of the registering openings 26 andl 46. When connecting the cases with the boxes, a filler strip 54 of rubber or other suitable packing material is to be disposed between the marginal edges of the contacting faces, as shown to advantage at Figure 7, to obtain anl approximately air-tight connection between the units. As illustrated at Figure 7, the cases C will assume positions elevated above the'iiooring of the store in which the refrigerator is assembled.l

Whenthus connected, the assembled structure provides an alternate arrangement of ice and provision chambers presenting a structure which may be effectivelyr employed as a counter and as a display case for displaying provisions and various commodities disposed in the provision chambers of therefrgerator. Each of the containers Aand B is to 'be substantially lled with ice or '.other Vform` of cooling medium. The auxiliary so that ice may bepacked into the container A- to a levelsubstantially above that of the cases. This construction is designed to assure effective circulation of cool air through the upper parts of the cases, the stream of air iiowing, as indicated by the arrows in Figure7,from the mastercontainerl alongthe u'p'perV sections of the cases while the end auxiliary containers B supply air currents flowing through the lower and intermediate portions `of vthe provision chambers.

vIt will-also be noted that during use of the refrigerator a's'upply of cool air will be maintained in the'compartments 30 of the ice containers as Well as the compartments 48 of the cases, the air beingsupplied thereto through the vents 31 and 50 respectively from the exterior of the refrigerator. When the filling door 25 of an ice container unit is opened for charging the container with ice, the escape of cold air from the ice' chamber will berlargely compensated for by the inrush of cooled air from the compartment 30 thereing-the-cool air of the compartment being Yreplaced bythe warm air from the exterior. When the filling operation is completed and the door closed,vthe pressure effected by the closure ofthe door will cause -a dischargeY of the warm airaccumulated in the compartment 30 and will replace, or partiallyreplace, the same with the cold air from the ice chamber. Similar'action is caused upon the opening of one of the doors of the provision cases, the compartment 48 serving as a reservoir for cooled air which is drawn into the provision chamber'when the doorv is opened. Upon closure of the Adoor the Awarm air,

' which has temporarily replaced the cool-air in the reservoir, is forced outwardly through the duct by cold' air 50 1and replaced 'or partially replaced from the provision chamber. f Y

'This-construction will greatly reduce the con sumptionof'eooling medium and obviate a substantial decrease in the temperature of the ice and provision chambers by opening the Ydoors thereof inasmuch asthe entrance of warm air to thesev chambers is largely-eliminated.

It will also be noted that the construction of the ice containers and provision units will enable assembly in various forms. In Figure 2 'is shown an-angular assembly embodying a master two auxiliary ice-boxes'and apair of provision cases. It will become apparentthat various modications 'of assemblymay beeffectedzalong this Iine and that the number of units may be varied in accordance with the sizeofy refrigerator required. l

It is to be understood that the form of my in'- vention herein shown and described is to be taken as a preferred example of the same, and that various changes as to the shape, size and arrangement of parts may be resorted to Without departing from the spirit of the invention or the in side walls of the containers, means for detachably connecting the ends of the cases against a side wall of the respective containers, and doors attached to the said containers and cases.

2. In a refrigerator, the combination of a relatively high master ice container having openings in side walls thereof, a plurality of auxiliary ice containers of reduced height relative to the masterrcontainer having openings in side Walls thereof, a plurality of provision cases having openings at the ends disposed to register with the openings in side walls of the' containers, means for detachably connecting the ends of the cases against a side wall of the respective containers, doors attached to the said containers and cases, and covers for enclosing unused side Wall openings of the containers. l
